• Integrated EMC Protection: Features built-in interference suppression, significantly reducing the complexity of panel design and cabling by mitigating conducted electromagnetic noise at the source.
• Mains Versatility: Designed for 3-phase 230 V industrial power networks, offering robust performance in environments where this voltage standard is utilized.
• Modular Interface: Fully compatible with the 8200-series modular ecosystem, allowing for the quick attachment of fieldbus communication cards or expanded I/O modules to meet specific process control requirements.

Technical Specifications

Frequently Asked Questions

Does the integrated interference suppression eliminate the need for external filtering?

In many standard industrial applications, the integrated suppression is sufficient to meet CE and EMC requirements. However, always consult the specific EMC manual for your installation, as extremely sensitive environments may still require supplemental external filtering.

Can I replace a different 8200-series model with the E82EV752_4C200?

The 8200-series is designed for modularity, but you must ensure that the voltage class (230 V) and power rating (7.5 kW) match your motor's specifications. Replacing a drive with a different power rating will lead to performance issues or drive fault trips.

How does this drive handle integration with modern PLCs?

This drive is highly versatile. It can be controlled via simple analog/digital signals or through the 8200-series fieldbus expansion modules (such as CANopen or Profibus), which allows for high-speed data exchange with modern PLCs.

Engineering Integration and Operational Safety

• Thermal Management: Despite the unit's high performance, it is vital to maintain adequate cabinet airflow. Mount the drive vertically with a minimum clearance of 100 mm above and below the housing. In high-ambient temperature environments, forced-air cooling is required to prevent thermal derating.
• Grounding Requirements: To ensure the efficacy of the internal interference suppression, connect the drive's PE terminal to the cabinet’s main ground bus using a low-impedance, short-run ground strap.
• Shielding Best Practices: Even with internal suppression, use shielded motor cables and ensure a 360-degree connection to the drive’s output terminal block. This prevents high-frequency common-mode noise from circulating through the machine frame.
• Commissioning Note: Perform a full motor auto-tuning process upon initial installation. This allows the drive to calibrate itself to the specific electrical characteristics of your motor, which is essential for accurate vector control performance.
